[0180] Implementation methods of this application

[0181] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0182] To facilitate understanding of the heater interconnection system, data communication method, and antenna module provided in the embodiments of this application, the application scenarios of the relevant solutions will be described below. Specifically, the heater described in this application refers to a type of device that heats substances through internal functional modules to generate various aerosols. It is currently widely used in various industries to meet the diverse needs of consumers. For example, heaters can be used as medical auxiliary equipment for doctors to use in treating patients.

[0183] However, due to factors such as market trends, equipment control, and costs, some heaters cannot or are inconvenient to configure remote communication functions. Therefore, to improve the user experience of such heaters, it is usually necessary to rely on a smartphone to enable communication between the heater and an external network. This is for data synchronization, analysis and pushing healthier lifestyle suggestions to users, recommending preferred products, software / system updates, and so on. However, this method relies on the interconnection between the heater and the smartphone, making it difficult to guarantee a stable and reliable connection between the heater and the external network. For example, when the smartphone and heater are no longer in close proximity, or when the smartphone's short-range communication function, such as Bluetooth, is forgotten to be turned on, the networking and intelligence of the heater will be significantly reduced, thus affecting the user experience.

[0184] To address the aforementioned technical problems, this application provides a heater interconnection system, a data communication method, and an antenna module. Based on the interconnection between heaters, it solves a current shortcoming in the heater market. This heater interconnection system allows companies to better manage their manufactured heater equipment. Even for heaters that are not easily configured with remote communication capabilities, data collection can be achieved. It provides a wealth of data information, particularly for sales, production, after-sales service, R&D, and technology iteration, enabling faster, more accurate, and more comprehensive solutions to heater equipment problems. This significantly benefits corporate image, enterprise management, and enhancing customer loyalty. Specifically, for a clearer understanding of the heater interconnection system, data communication method, and antenna module provided in this application's embodiments, please refer to Figure 1a. Figure 1a is a schematic diagram of the structure of a heater interconnection system provided in this application's embodiments, detailed below.

[0185] Specifically, the heater interconnection system provided in this application embodiment includes multiple heaters, wherein the heaters include at least one first-type heater 170 and at least one second-type heater 180. For example, as shown in the figure, there is one first-type heater 170 and three second-type heaters 180. Of course, the number of each type of heater in the heater interconnection system shown in the figure is only one feasible embodiment and should not be construed as a limitation of this application. In fact, the heater interconnection system may also include more or fewer heaters than shown in the figure. As long as the heater interconnection system includes at least one first-type heater 170 and one second-type heater 180, it is within the scope of protection claimed in this application. It should be particularly noted that the heater interconnection system provided in this application is usually composed of multiple heaters produced by the same manufacturer and can be used for data collection from multiple heaters produced by the same manufacturer. Alternatively, it can be composed of heaters produced by multiple manufacturers that have reached a pre-agreed agreement. Any heater that can identify the identification information of other heaters through certain communication technologies to form a network for communication can be used to constitute the heater interconnection system provided in this application. Furthermore, the second-type heater in the heater interconnection system refers to a type of heater, and its specific number will change dynamically.

[0186] Based on the foregoing, the second type of heater 180 is used to send usage data of the second type of heater to the first type of heater when it is within the communication distance of the first type of heater 170.

[0187] Specifically, the usage data typically includes the heater's actual operating status, energy consumption, temperature data, battery charge changes and degradation data, etc. That is, the second type of heater can upload the above usage data to the first type of heater 170 in a given data format.

[0188] Of course, in another embodiment, the second type of heater includes multiple heaters. In this case, the second type of heater can also receive usage data from other second type of heaters while within the communication range of other second type of heaters, and / or send its own usage data to other second type of heaters. For example, the second type of heater can receive usage data from other second type of heaters, and while within the communication range of the first type of heater, send the received usage data from other second type of heaters along with its own usage data to the first type of heater. That is, after receiving usage data from other second type of heaters, the second type of heater can also send the received usage data from other second type of heaters to the first type of heater while within the communication range of the first type of heater.

[0189] Alternatively, after the second type of heater sends its own usage data to other second type of heaters, the other second type of heaters can also upload the received usage data to the first type of heater, provided that the other second type of heaters are within the communication range of the first type of heater.

[0190] Of course, in addition to uploading the usage data received from the second type of heater, the first type of heater can also upload its own usage data.

[0191] Specifically, based on the aforementioned heater interconnection system, please refer to Figure 1b, which is a schematic diagram of another heater interconnection system provided in the embodiment of this application. Compared with the heater interconnection system shown in Figure 1a, the system further includes a server 190. In particular, the server can typically communicate with the first type of heater 170.

[0192] Specifically, in this embodiment of the application, the first type of heater 170 is used to upload the received usage data of the second type of heater 180 to the server 190;

[0193] The server 190 is also used to display and / or process the received usage data of at least one heater, wherein the received heater usage data includes usage data of a first heater and / or usage data of a second heater.

[0194] For example, server 190 can display the usage data of a heater, so that the back-end administrator of server 190 can determine the heater's faults based on the heater's usage data, realize remote diagnosis of the heater, and improve the user experience.

[0195] Alternatively, the server-side 190 can analyze the heater's usage data based on a pre-configured algorithm to determine reasonable recommendations for the heater's use, such as configuring a specific heating curve for the heater to improve its performance.

[0196] In addition, the server 190 can also synchronize the heater's data in real time, such as updating the heater's system or software.

[0197] Of course, it should be noted that in the above process, the usage data received by the server 190 usually also carries the identification information of the heater corresponding to the usage data, so that the server 190 can better organize and analyze the heater usage data.

[0198] Furthermore, it should be noted that since the second type of heater 180 in the heater interconnection system cannot communicate directly with the server 190, it often needs to transmit usage data to the first type of heater 170 in order to upload the usage data to the server 190. However, considering that the heater interconnection system provided in this application can be understood as a mobile network, meaning that the first and second type heaters included in a certain heater interconnection system are not fixed, the processed data after the server 190 processes the usage data of the second type of heater 180, such as update data, recommendation data, configuration data, etc., cannot be transmitted to the corresponding second type of heater 180 through the fixed first type of heater 170. Therefore, in one embodiment of this application, the heater often requests the corresponding data from the server 190 through a data request. Specifically, the first type of heater 170 is also used to send request data to the server 190, and the server 190 is also used to receive the request data sent by the first type of heater 170. The request data carries at least the identification information of a target heater, which can be the first type of heater 170 or a second type of heater 180 that is within the communication distance of the first type of heater 170.

[0199] At this time, after receiving the request data, the server 190 also retrieves the target processing data from the database based on the identification information and sends the target processing data to the first type of heater. The target processing data is the processing data after processing the target usage data of the target heater. The target processing data is used to control the target heater. For example, it can update the target heater system or software, or recommend the configuration of the heating curve of the target heater, etc.

[0200] Furthermore, the first type of heater is also used to forward the received target processing data to the target heater.

[0201] In this embodiment, the server 190 is typically a standalone server, or it can be a service cluster consisting of multiple servers. Furthermore, the server 190 can also be located in the cloud; this embodiment does not impose any limitations on the server 190. Specifically, the server 190 is typically configured with a corresponding management system for managing multiple heaters within the heater interconnection system provided in this application. The management system is typically implemented using a specific programming language, which will not be elaborated upon in this embodiment.

[0202] Of course, in order to realize data communication between multiple heaters in the heater interconnection system, as well as communication between the first type of heater and the server, please refer to Figure 1c. Figure 1c is a schematic diagram of another heater interconnection system provided in an embodiment of this application, which is described in detail below.

[0203] Specifically, in the embodiments of this application, the first type heater 170 and the second type heater 180 are typically equipped with a first communication component 171. Multiple heaters can communicate with each other through the first communication component 171 when they are within a certain communication distance, so that the first type heater 170 in the system can collect usage data of at least one second type heater 180.

[0204] In addition, the first type of heater may also be configured with a second communication component 181, wherein the second communication component 181 is mainly used for communication between the first type of heater 170 and an external network. For example, it can upload the first usage data of the first type of heater 170 and / or the data of at least one second type of heater 180 collected, for example, to a server.

[0205] Specifically, in one embodiment of this application, the first communication component 171 is a communication component that supports near-field communication (NFC). For example, as a feasible implementation, the first communication component 171 can be a near-field communication chip for implementing near-field communication (NFC) between heaters. The first communication component 171 can also be a Bluetooth module for implementing Bluetooth communication connections between heaters. Furthermore, the first communication component 171 can also be a Wi-Fi module for implementing Wi-Fi connections between heaters. Of course, communication components supporting other near-field communication technologies are also feasible, and this embodiment of the application does not impose limitations. Considering the specific application scenario of the heaters, i.e., the heaters are usually in high-frequency movement and usually need to maintain a certain distance, as a feasible implementation of this application, the first communication component 171 can be a Bluetooth module. In particular, the first communication component 171 can also be a Bluetooth Low Energy (BLE) module.

[0206] Correspondingly, the second communication component 181 is a communication component that supports long-distance communication. For example, the second communication component 181 can be a cellular communication module to support cellular communication technologies such as LTE (Long-Term Evolution), 4G (Fourth Generation Mobile Communication System), and 5G (Fifth Generation Mobile Communication System). The second communication component 181 can also be a satellite communication module to support satellite communication technology. In addition, the second communication component 181 can also be a long-range low-power wireless module (LoRa). Of course, considering the specific application scenario of the heater and the requirements for data transmission bandwidth, the second communication component 181 can be a cellular communication module, and in particular, a cellular communication module that supports LTE cellular communication technology can be selected.

[0207] Furthermore, in one embodiment of this application, the first type of heater and the second type of heater are aerosol generating devices, that is, the heating module can be used to heat the substance to generate the corresponding aerosol for the purpose of treatment or consumption by the user.

[0208] Specifically, the first type of heater is typically a non-combustible aerosol generator, while the second type of heater is a misting aerosol generator. Both types of heaters can be used in home environments, and also in public places. For example, by integrating usage data of the second type of heater collected in public places and uploading it to a server, the first type of heater can be used to remotely monitor heater usage in public areas.

[0209] Of course, in order to clearly understand the heater interconnection system provided in the embodiments of this application, please refer to Figure 2. Figure 2 is a schematic diagram of a complete application scenario of a heater interconnection system provided in the embodiments of this application, which is described in detail below.

[0210] In this embodiment, devices A to G can generally be considered as the second type of heater in the heater interconnection system, such as an atomizing heater, while device H can be considered as the first type of heater in the heater interconnection system, such as a non-combustible heater. Both devices have BLE Mesh (Bluetooth Low Energy Mesh Network) functionality. However, due to ID restrictions and market trends, devices A to G cannot be configured with LTE functionality, while device H can be configured with both BLE Mesh and LTE functionality. The LTE functionality equipped in device H enables mobile interconnection around the world. Wherever there is a base station, background interaction can be achieved, and it assists devices A to G in uploading usage data to the server.

[0211] By joining a BLE Mesh network, customers can leverage the characteristics of mesh networking to form a star network. This allows usage data from more distant devices to be transmitted to device H via an intermediary device. For example, data from devices A and B can be transmitted sequentially via BLE Mesh to devices D and F, and then to device H. Finally, device H uploads the data to a server via a base station, where a management system configured on the server performs further data processing. This completely avoids the communication limitations imposed by the limited connection distance of pure BLE. It also enables better monitoring and management of device information, providing consumers with useful information.

[0212] Device H has both BLE Mesh and LTE capabilities and can be considered as a provisioner in the system. It is used to manage network members within the system, such as other Class II heaters, thereby transferring and uploading network member information. It can achieve fully automated and intelligent management without relying on user operation.

[0213] Furthermore, it should be noted that, compared to systems with fixed network members, the heater interconnection system provided in this application is filled with mobile members—that is, different members may or may not connect to the system. Therefore, in order to better identify members within the system, this application also employs a networking method, namely a data communication method, to effectively ensure the disconnection and connection of each network member within the system, thereby effectively collecting data from the heater devices within the network. The specific data communication method will be described in detail in subsequent embodiments.

[0214] Please refer to Figure 3, which is a flowchart illustrating the steps of a data communication method provided in an embodiment of this application. This flowchart primarily operates on a second type of heater in a heater interconnection system. Specifically, the method includes step S310:

[0215] S310, when within the communication range of the first type of heater, upload its own usage data to the first type of heater.

[0216] In this embodiment of the application, when the second type of heater detects that it is within communication distance of the first type of heater, it will attempt to establish a communication connection with the first type of heater, thereby uploading the usage data stored and recorded by itself to the first type of heater.

[0217] Building upon the foregoing, the second type of heater, in addition to seeking a direct communication connection with the first type of heater, can also seek communication connections with other second type of heaters, thereby enabling the transfer of usage data between them. This ensures that usage data from multiple second type of heaters can ultimately be transmitted to the first type of heater. In other words, in one embodiment, the method further includes:

[0218] When within the communication range of other Class II heaters, receive usage data from other Class II heaters, and / or send its own usage data to other Class II heaters.

[0219] Specifically, the transmission of usage data between different types of heaters is determined based on the state of each type of heater. For example, if a type of heater can communicate directly with a type of heater or indirectly with another type of heater, it can be considered to be in a linked state. Conversely, if a type of heater cannot transmit data directly or indirectly to a type of heater, it can be considered to be in a disconnected state. Of course, the linked and disconnected states of a type of heater can be switched based on the actual scenario.

[0220] Specifically, when a second-type heater receives usage data from other second-type heaters, it typically requires that it be in a chain state, meaning it can directly or indirectly transmit the data to the first-type heater. In other words, receiving usage data from other second-type heaters includes:

[0221] While in a chained state, it receives usage data from other Class II heaters.

[0222] Thus, after receiving usage data from other second-class heaters, the received usage data can be directly uploaded to the first-class heater, for example, if it is within the communication distance of the first-class heater, or the usage data can be transmitted to other second-class heaters in a chained state, so that the usage data is eventually uploaded to the first-class heater.

[0223] When a heater is in a chainless state, if other second-type heaters are in a chained state, it can send its own usage data to the other second-type heaters, so that the other second-type heaters can directly or indirectly upload the received usage data to the first-type heater.

[0224] Of course, when both the second type of heaters are in a chainless state, they will not transmit data between themselves because neither of them can directly or indirectly upload the usage data to the first type of heater.

[0225] It is understandable that after a second-type heater sends its own usage data to other second-type heaters, considering that the other second-type heaters are in a chained state, and the heater itself has established a communication connection with the first-type heater, it can be assumed that the second-type heater is also in a state where it can indirectly upload its usage data to the first-type heater. Therefore, after the step of sending its own usage data to other second-type heaters (assumed to be identified as 1 for distinction), the method further includes:

[0226] Set its own working state to a chained state.

[0227] After setting its own working state to the chained state, and further scanning for other second-class heaters (assumed to be labeled 2 for distinction), it can receive the usage data of other second-class heaters (labeled as second-class heater 2) in the non-chained state, then re-establish communication with the other second-class heater labeled as 1, and upload the received usage data of the second-class heater labeled as 2 to the second-class heater labeled as 1, thus finally uploading it to the first-class heater.

[0228] Of course, considering the hierarchical relationship between data, when a heater is already in a linked state, its linked level can be further configured. The linked level can be understood as the number of times a second-type heater needs to transmit data to a first-type heater. For example, for a second-type heater within the communication distance of a first-type heater, its level can be set to 1; for other second-type heaters within the communication distance of this first-type heater, its linked level can be further set to 2. In other words, when a heater is already in a linked state, its own linked level is updated based on the linked levels of other second-type heaters.

[0229] Of course, when a Type II heater can no longer transmit data directly or indirectly to a Type I heater, it can further set its operating state to a chainless state. For example, when it is outside the communication range of other Type II heaters, i.e., when the connection with other Type II heaters is disconnected, or when it receives preset data from other Type II heaters, such as receiving a broadcast message from another Type II heater indicating that it is no longer in a chained state, it will also set its operating state to a chainless state. Simultaneously, after setting to a chainless state, it will broadcast the information that it is no longer in a chained state.

[0230] Of course, when a second type heater is directly within the communication range of a first type heater, that is, when it can directly communicate with the first type heater, the second type heater will also set its working state to the chained state. At the same time, when it is outside the communication range of the first type heater, it will set its working state to the chainless state.

[0231] In other words, in this embodiment, each second-type heater can determine whether it can upload data to the first-type heater by its own operating state being either linked or unlinked. This flexible switching of operating states enables flexible networking between multiple second-type heaters and the first-type heater. Specifically, a second-type heater will only set itself to a linked state and further absorb other second-type heaters into the system network if it joins a network that can directly or indirectly communicate with the first-type heater. Conversely, if a second-type heater disconnects its direct or indirect communication with the first-type heater, it will also set itself to an unlinked state and broadcast the change, allowing other heaters that transmit data to the first-type heater through that second-type heater to synchronously update their own states. This achieves flexible networking between multiple second-type heaters and the first-type heater.

[0232] Of course, it should be noted that the method described above is only used as an example of transmitting usage data. In fact, this data communication method is also applicable to the transmission of request data by the second type of heater. That is, by transmitting the request data to the first type of heater, the first type of heater can upload the request data to the server and receive the processing data returned by the server, and then send it back to itself to realize its own control, such as system software updates and other operations.

[0233] Of course, as another type of heater provided in this application, this application also provides a schematic diagram of the steps of another data communication method. Specifically, please refer to Figure 4. This step process mainly operates on the first type of heater in the heater interconnection system, wherein the method specifically includes steps S410 to S420:

[0234] S410, when within the communication range of the second type of heater, receives usage data uploaded by the second type of heater.

[0235] In this embodiment, the usage data uploaded by the second type of heater may be its own usage data, or it may be usage data received from other second type heaters. This embodiment does not limit the usage data uploaded by the second type of heater received. However, for ease of data organization, this usage data usually also carries the identification information of the corresponding heater.

[0236] S420, upload the usage data of the second type of heater.

[0237] In this embodiment of the application, the first type of heater will also continuously upload the usage data of the second type of heater received. For example, in one embodiment, the data is uploaded to the server for display, processing or unified management.

[0238] Furthermore, the first type of heater can also upload its own usage data to the cloud.

[0239] Of course, in addition to using data, the first type of heater can also receive request data uploaded by the second type of heater, upload it to the server, and receive processing data from the server, then transmit it to the corresponding heater. This application will not elaborate further on this.

[0240] The data communication method provided in this application embodiment enables flexible networking of multiple heaters within a heater interconnection system, thereby improving network connectivity and effectively collecting a wide range of data.

[0241] Furthermore, it should be noted that since the heaters provided in this application are typically small and portable, it is also necessary to effectively ensure the communication performance of the heaters within the heater interconnection system. Therefore, the embodiments of this application further design an antenna module deployed on the heater. Specifically, as shown in Figure 5, an antenna module is provided for assembly into the heater, wherein the heater can be one of the heaters in the heater interconnection system provided in any of the foregoing embodiments. Specifically, the antenna module includes a cellular IoT antenna and a cellular radio frequency transceiver unit.

[0242] The cellular IoT antenna is electrically connected to the cellular radio frequency transceiver unit, and is used to feed back cellular electromagnetic wave signals received from the outside to the cellular radio frequency transceiver unit and to transmit cellular radio frequency signals output by the cellular radio frequency transceiver unit to the outside.

[0243] Among them, a cellular IoT antenna can be a single cellular radiator or a collection of multiple cellular radiators.

[0244] The antenna module in this application is equipped with a cellular IoT antenna and a corresponding cellular radio frequency transceiver unit. Through the cellular radio frequency transceiver unit, cellular electromagnetic wave signals received from the outside can be fed back to the cellular radio frequency transceiver unit and cellular radio frequency signals output by the cellular radio frequency transceiver unit can be transmitted to the outside, thus realizing cellular IoT communication.

[0245] As shown in Figure 6a, the cellular IoT antenna is composed of a first cellular radiator, and its frequency coverage includes low frequency and mid-to-high frequency.

[0246] As shown in Figure 6b, optionally, the cellular IoT antenna includes a first cellular radiator and a second cellular radiator, wherein the radio frequency range covered by the first cellular radiator is different from that of the second cellular radiator.

[0247] The first and second cellular radiators are electrically connected to the cellular radio frequency transceiver unit, respectively.

[0248] The radio frequency range covered by the first cellular radiator can correspond to the low frequency range, such as the 703MHz to 960MHz band; the radio frequency range covered by the second cellular radiator can correspond to the mid-to-high frequency range, such as the 1710MHz to 2690MHz band.

[0249] In this embodiment, the first cellular radiator serves as the first cellular antenna, and the second cellular radiator serves as the second cellular antenna.

[0250] As shown in Figure 7, optionally, the antenna module may also include a signal selection unit.

[0251] The signal selection unit is electrically connected to the cellular radio frequency transceiver unit, the first cellular radiator, and the second cellular radiator, respectively, and is used to select the radio frequency signals between the first cellular radiator and the second cellular radiator. Generally speaking, the signal selection unit has isolation characteristics between the first cellular radiator and the second cellular radiator to ensure that the radio frequency signals entering the cellular radio frequency transceiver unit from the first cellular radiator and the second cellular radiator do not interfere with each other. Typical types of signal selection units include switching switches, combiners, etc.

[0252] When two cellular radiators are used to transmit signals with the same cellular radio frequency transceiver unit, the radio frequency signals transmitted by the two cellular radiators are prone to mutual interference. Furthermore, impedance matching between the cellular radio frequency transceiver unit and the two cellular radiators is difficult to achieve. Theoretically, it is possible to design the two cellular radiators in a highly complex way to prevent mutual interference between their respective radio frequency signals and to ensure impedance matching between the two cellular radiators and the cellular radio frequency transceiver unit, but this approach is difficult to implement.

[0253] Therefore, in this embodiment, a signal selection unit is added to address this situation, allowing the first and second cellular radiators to transmit signals to the cellular radio frequency transceiver unit through the signal selection unit. By utilizing the isolation characteristics of the signal selection unit, the design difficulty of the first and second cellular radiators is reduced.

[0254] As shown in Figure 8, optionally, the signal selection unit includes a switching switch.

[0255] The first access terminal of the switch is electrically connected to the cellular radio frequency transceiver unit, the second access terminal of the switch is electrically connected to the first cellular radiator, and the third access terminal of the switch is electrically connected to the second cellular radiator.

[0256] The switching device can be any type of electronic switch, mechanical switch, microelectromechanical switch, integrated circuit switch, etc.

[0257] The switch is used to select the line between the cellular radio frequency transceiver unit and the first cellular radiator or the line between the cellular radio frequency transceiver unit and the second cellular radiator.

[0258] When the switch selects the line between the cellular radio frequency transceiver unit and the first cellular radiator, the first cellular radiator and the cellular radio frequency transceiver unit can transmit signals normally. If the first cellular radiator is responsible for the low frequency range, the antenna module can then achieve low-frequency cellular IoT communication with the outside.

[0259] When the switching switch selects the line between the cellular radio frequency transceiver unit and the second cellular radiator, the second cellular radiator and the cellular radio frequency transceiver unit can transmit signals normally. If the second cellular radiator is responsible for the mid-to-high frequency range, the antenna module can then achieve mid-to-high frequency cellular IoT communication with the outside.

[0260] Since only one cellular radiator and the cellular radio frequency transceiver unit are connected at any given time, meaning only one radio frequency signal is transmitted, there will be no problem of mutual interference between the two radio frequency signals.

[0261] As shown in Figure 9, optionally, the signal selection unit includes a signal combiner.

[0262] The first access terminal of the signal combiner is electrically connected to the cellular radio frequency transceiver unit, the second access terminal of the signal combiner is electrically connected to the first cellular radiator, and the third access terminal of the signal combiner is electrically connected to the second cellular radiator.

[0263] Among them, the signal combiner can enable the simultaneous transmission of two radio frequency signals and can isolate the two radio frequency signals.

[0264] Optionally, the signal combiner includes a first filter and a second filter, wherein the first filter allows a different range of radio frequency frequencies than the second filter.

[0265] For the signal combiner, the first access terminal of the first filter and the first access terminal of the second filter are the same terminal and are electrically connected to the cellular radio frequency transceiver unit. The second access terminal of the first filter is electrically connected to the first cellular radiator, and the second access terminal of the second filter is electrically connected to the second cellular radiator.

[0266] If the first cellular radiator is responsible for the low-frequency range, then the first filter can be understood as a low-frequency filter with a passband range of low frequency, such as the 703MHz to 960MHz band. Similarly, if the second cellular radiator is responsible for the mid-high frequency range, then the second filter can be understood as a mid-high frequency filter with a passband range of mid-high frequency, such as the 1710MHz to 2690MHz band.

[0267] As shown in Figure 10, optionally, the cellular radio frequency transceiver unit includes a first transceiver subunit and a second transceiver subunit.

[0268] The first transceiver subunit is electrically connected to the first cellular radiator, and the second transceiver subunit is electrically connected to the second cellular radiator.

[0269] As mentioned in the above embodiments, when the first cellular radiator and the second cellular radiator transmit radio frequency signals with the same cellular radio frequency transceiver unit, the two radio frequency signals are prone to mutual interference. In the above embodiments, to solve this problem, a switching switch or signal combiner can be added as a signal selection unit. The isolation characteristics of the signal selection unit are utilized to achieve the purpose of signal isolation.

[0270] In this embodiment, corresponding first and second transceiver subunits can be set up for the first and second cellular radiators, respectively. This ensures that the first transceiver subunit transmits radio frequency signals only with the first cellular radiator, and the second transceiver subunit transmits radio frequency signals only with the second cellular radiator. Since neither the first transceiver subunit nor the first cellular radiator, nor the second transceiver subunit nor the second cellular radiator, experiences simultaneous transmission of two radio frequency signals, the aforementioned signal interference problem can be resolved.

[0271] As shown in Figure 11, optionally, the antenna module also includes a first cellular feed unit and a coupling tuning unit.

[0272] The first cellular feed unit is electrically connected to the cellular radio frequency transceiver unit and the first cellular radiator, respectively, and the coupling and tuning unit is electrically connected to the first cellular radiator and the second cellular radiator, respectively.

[0273] The second honeycomb radiator is a parasitic unit of the first honeycomb radiator.

[0274] The first cellular feed unit is mainly used to achieve impedance matching between the cellular RF transceiver unit and the first cellular radiator, thereby improving the reliability of signal transmission. In this embodiment, the second cellular radiator is not directly electrically connected to the cellular RF transceiver unit, but is coupled to the first cellular radiator through a coupling tuning unit, thus acting as a parasitic unit of the first cellular radiator to enhance the overall antenna performance.

[0275] In this embodiment, the coupling tuning unit is mainly used to adjust the coupling strength between the first honeycomb radiator and the second honeycomb radiator, thereby achieving the purpose of adjusting the overall performance of the first honeycomb radiator and the second honeycomb radiator.

[0276] As shown in Figure 12a, the antenna module also includes a second cellular tuning unit that is electrically connected to the second cellular radiator.

[0277] The second cell tuning unit is used to form a loop between the second cell radiator and the ground terminal, thereby achieving the purpose of frequency adjustment of the second cell radiator and improving the frequency coverage performance of the second cell radiator.

[0278] [Corrected according to Rule 91, 27.02.2026] As shown in Figure 12b, the first cellular radiator is realized through the resonance of the low-frequency radiator, and the second cellular radiator is realized through the resonance of the mid-to-high-frequency parasitic radiator. The first cellular feed unit and the cellular RF transceiver unit can be simplified to the first feed point, the coupling tuning unit can be simplified to the coupling tuning point, and the second cellular tuning unit can be simplified to the mid-to-high-frequency tuning point. It should be noted that the first feed point in Figure 12b is electrically connected to the low-frequency radiator on one hand and electrically connected to ground on the other hand, which is the basis for realizing RF signal transmission.

[0279] In other embodiments, the cellular radio frequency transceiver unit includes a first transceiver subunit and a second transceiver subunit, and the antenna module further includes a signal selection unit.

[0280] The signal selection unit is electrically connected to the first transceiver subunit, the second transceiver subunit, and the first cellular radiator, respectively, and is used to select the radio frequency (RF) signal between the first and second transceiver subunits. Whether the first cellular radiator directly constitutes the cellular IoT antenna and independently handles low-frequency and mid-to-high-frequency RF signals, or whether the first cellular radiator acts as the main radiator and combines with the second cellular radiator (as a parasitic unit) to form the cellular IoT antenna and jointly handle low-frequency and mid-to-high-frequency RF signals, when the cellular RF transceiver unit has two transceiver subunits, both subunits will transmit RF signals with the same cellular IoT antenna, which can easily lead to signal interference. The signal selection unit enables signal selection and utilizes its isolation characteristics to solve the interference problem.

[0281] As shown in Figure 13a, the signal selection unit can be a switching switch; or as shown in Figure 13b, the signal selection unit can be a combiner.

[0282] In both Figure 13a and Figure 13b, the cellular IoT antenna shown can include either a single first cellular radiator or a first cellular radiator as the main radiator and a second cellular radiator as a parasitic unit.

[0283] As shown in Figure 14, optionally, the antenna module also includes a cellular feed unit.

[0284] The cellular feed unit is electrically connected to both the cellular IoT antenna and the cellular RF transceiver unit.

[0285] The cellular feed unit can include devices and / or chips such as capacitors, inductors, resistors, ferrite beads, antenna switches, antenna tuners, variable capacitors, and variable inductors, or it can be a circuit composed of these devices and / or chips. There are no specific restrictions on the topology of the cellular feed unit. It can be selected based on the characteristics of the return loss before antenna matching. Typical topologies include L-type, π-type, multi-level L-type cascade, multi-level π-type cascade, and multi-level L-type and π-type cascade.

[0286] In Figure 14, a cellular IoT antenna can include either one cellular radiator or two cellular radiators. When two cellular radiators are included, the first cellular radiator can serve as the main radiator, and the second cellular radiator can serve as a parasitic unit, thus forming a cellular antenna together.

[0287] As shown in Figure 15a, optionally, when there are two cellular radiators, there are two cellular feed units, namely a first cellular feed unit and a second cellular feed unit.

[0288] The first cellular feed unit is electrically connected to the cellular radio frequency transceiver unit and the first cellular radiator, respectively, and the second cellular feed unit is electrically connected to the cellular radio frequency transceiver unit and the second cellular radiator, respectively.

[0289] As mentioned in the above embodiments, the second cellular radiator can serve as a parasitic unit of the first cellular radiator through a coupling tuning unit, thus requiring only a first cellular feed unit between the cellular RF transceiver unit and the first cellular radiator for impedance matching. In this embodiment, when the cellular RF transceiver unit includes a first transceiver subunit and a second transceiver subunit corresponding to the first and second cellular radiators respectively, the second cellular radiator can operate independently. In this case, the second cellular radiator needs to be electrically connected to the second transceiver subunit through a corresponding second cellular feed unit.

[0290] As a supplement, when there is only one cellular radio frequency transceiver unit, and it transmits radio frequency signals to both the first cellular radiator and the second cellular radiator simultaneously, the first cellular radiator is electrically connected to the cellular radio frequency transceiver unit through the first cellular feed unit, so that the first cellular radiator can work independently as a cellular antenna; similarly, the second cellular radiator is electrically connected to the cellular radio frequency transceiver unit through the second cellular feed unit, so that the second cellular radiator can work independently as a cellular antenna.

[0291] As shown in Figure 15a, optionally, the antenna module may also include a coupling and tuning unit.

[0292] The coupling tuning unit is coupled to the first honeycomb radiator and the second honeycomb radiator respectively.

[0293] In this embodiment, unlike the previous embodiment, since the second honeycomb radiator works independently, the coupling tuning unit is mainly used to adjust the coupling strength between the first honeycomb radiator and the second honeycomb radiator, thereby achieving the purpose of adjusting the overall performance of the first honeycomb radiator and the second honeycomb radiator.

[0294] As shown in Figure 15b, the first cellular radiator is realized through the resonance of the low-frequency radiator, and the second cellular radiator is realized through the resonance of the mid-to-high frequency radiator. The first cellular feed unit and the first transceiver subunit can be simplified to the first feed point, the second cellular feed unit and the second transceiver subunit can be simplified to the second feed point, and the coupling tuning unit can be simplified to the coupling tuning point.

[0295] Optionally, any cellular feed unit may include a cellular feed selection subunit and multiple cellular feed units.

[0296] For each cellular feed unit, a cellular feed selection subunit and multiple cellular feed electronic units are electrically connected to the cellular IoT antenna and the cellular RF transceiver unit, respectively, to electrically connect different numbers of cellular feed electronic units in series and / or parallel between the cellular IoT antenna and the cellular RF transceiver unit.

[0297] Specifically, as shown in Figure 15c, the cellular feed unit includes a first cellular feed unit, a second cellular feed unit, an antenna switch, a first switch branch unit, a second switch branch unit, a third switch branch unit, and a fourth switch branch unit. The first switch branch unit, the second switch branch unit, the third switch branch unit, and the fourth switch branch unit can have the same composition as the cellular feed unit; that is, the first switch branch unit, the second switch branch unit, the third switch branch unit, and the fourth switch branch unit also serve as corresponding cellular feed units. Since they are connected to the antenna switch, they are referred to as "switch branch units".

[0298] Specifically, as shown in Figure 15d, the cellular feed unit includes a first cellular feed unit, a second cellular feed unit, a third cellular feed unit, an antenna switch, a first switch branch unit, a second switch branch unit, a third switch branch unit, and a fourth switch branch unit.

[0299] In Figures 15c and 15d, the cellular feed selection subunit is a single-pole four-throw antenna switch. In other embodiments, it can also be a variable capacitor or a variable inductor.

[0300] Regarding Figure 15c, when the antenna switch operates in different states, one or more units from the four switch branch units can be simultaneously connected to the parallel path of the cellular feed unit, allowing the cellular feed unit to exhibit different circuit characteristics as a whole, thereby obtaining different operating frequencies and / or radiation performances of the cellular IoT antenna. Furthermore, it is conceivable that as the number of switchable paths of the antenna switch increases, the operating frequency range that the cellular IoT antenna can cover, and the radiation performance it can exhibit, will have more options, better meeting the needs of cellular IoT communication systems. Additionally, different ways of integrating the antenna switch within the cellular feed unit can also result in different cellular feed unit circuit performances, bringing more redundancy to the overall system design.

[0301] For Figure 15d, the main difference from Figure 15c is that the fourth switch branch unit is introduced into the series path of the cellular feed unit to change the circuit state of the series path of the cellular feed unit, thereby bringing different ideas and design redundancy to the overall system design.

[0302] Based on the above-mentioned integrated antenna switch design concept, Figure 31 shows the curves of antenna return loss and total efficiency when the antenna switch is working in different states. As can be seen from the figure, for different working states of the antenna switch, the antenna will achieve good return loss and total efficiency in different working frequency bands, thereby meeting the overall requirements of the cellular Internet of Things communication system.

[0303] As a supplement, the coupling tuning unit mentioned in the above embodiments can also adopt the design concept of the same cell feed unit, and realize the dynamic adjustment of coupling tuning by setting corresponding coupling tuning selection sub-units and multiple coupling tuning sub-units.

[0304] As shown in Figure 14, optionally, the antenna module also includes a cellular tuning unit.

[0305] The cellular tuning unit is electrically connected to the cellular IoT antenna.

[0306] The cellular tuning unit is used to form a loop between the cellular IoT antenna and the ground terminal, thereby achieving the purpose of frequency adjustment of the cellular IoT antenna to improve the frequency coverage performance of the cellular IoT antenna.

[0307] The cellular tuning unit may include devices and / or chips such as capacitors, inductors, resistors, ferrite beads, antenna switches, antenna tuners, variable capacitors, and variable inductors, or it may be a circuit composed of these devices and / or chips.

[0308] It should be added that, in addition to impedance matching, the first and second cellular feed units can also further perform frequency adjustment. As shown in Figure 16a or Figure 17a, optionally, when the cellular IoT antenna includes a first and second cellular radiator, the antenna module also includes:

[0309] A first cellular tuning unit electrically connected to a first cellular radiator and a second cellular tuning unit electrically connected to a second cellular radiator.

[0310] The first cellular tuning unit forms a loop between the first cellular radiator and the ground terminal, thereby adjusting the frequency of the first cellular radiator to improve its frequency coverage performance. Similarly, the second cellular tuning unit forms a loop between the second cellular radiator and the ground terminal, thereby adjusting the frequency of the second cellular radiator to improve its frequency coverage performance.

[0311] In other embodiments, if the performance of the first cellular radiator itself is sufficient, the first cellular tuning unit can be omitted, and only the second cellular tuning unit can be retained. Similarly, in other embodiments, if the performance of the second cellular radiator itself is sufficient, the second cellular tuning unit can be omitted, and only the first cellular tuning unit can be retained.

[0312] As shown in Figures 16a and 16b, based on the parasitic radiator approach, the first cellular radiator is realized through the resonance of a low-frequency radiator, and the second cellular radiator is realized through the resonance of a mid-to-high frequency parasitic radiator. The first cellular feed unit and the cellular radio frequency transceiver unit can be simplified to a first feed point, the coupling tuning unit can be simplified to a coupling tuning point, the first cellular tuning unit can be simplified to a low-frequency tuning point, and the second cellular tuning unit can be simplified to a mid-to-high frequency tuning point.

[0313] As shown in Figures 17a and 17b, based on their respective independent methods, the first cellular radiator is realized through the resonance of a low-frequency radiator, and the second cellular radiator is realized through the resonance of a mid-to-high-frequency radiator. The first cellular feed unit and the first transceiver subunit can be simplified to a first feed point, the second cellular feed unit and the second transceiver subunit can be simplified to a second feed point, the coupling tuning unit can be simplified to a coupling tuning point, the first cellular tuning unit can be simplified to a low-frequency tuning point, and the second cellular tuning unit can be simplified to a mid-to-high-frequency tuning point.

[0314] Optionally, any cellular tuning unit may include a cellular tuning selection subunit and multiple cellular tuning subunits.

[0315] For each cellular tuning unit, a cellular tuning selection subunit and multiple cellular tuning subunits are electrically connected to the cellular IoT antenna and ground, respectively, to selectively connect different numbers of cellular tuning subunits to the cellular IoT antenna and ground.

[0316] The cellular tuning unit achieves dynamic adjustment of cellular tuning by setting up a cellular tuning selection subunit and multiple cellular tuning subunits. For details, please refer to the cellular power supply unit mentioned above, which will not be repeated here.

[0317] Furthermore, there are no fixed restrictions on the circuit topology for the aforementioned coupling tuning points, low-frequency tuning points, and mid-to-high-frequency tuning points. Additionally, depending on the actual antenna performance requirements, these tuning points can also be in an open-circuit or short-circuit state. Taking a tuning point as an example, in an open-circuit state, it can be considered as if the tuning point has been removed; in a short-circuit state, it can be considered as if the corresponding antenna radiator is directly connected to ground, or the low-frequency radiator and the mid-to-high-frequency radiator are directly connected.

[0318] As shown in Figure 18, optionally, the antenna module also includes a Bluetooth antenna, a Bluetooth power supply unit, and a Bluetooth radio frequency transceiver unit.

[0319] The Bluetooth antenna is electrically connected to the Bluetooth RF transceiver unit via the Bluetooth power supply unit.

[0320] The Bluetooth antenna is used to feed back Bluetooth electromagnetic wave signals received from the outside to the Bluetooth radio frequency transceiver unit and to transmit Bluetooth radio frequency signals output by the Bluetooth radio frequency transceiver unit to the outside.

[0321] As shown in Figure 19, optionally, the antenna module may also include a cellular processing unit and a Bluetooth processing unit.

[0322] The cellular processing unit includes an LB (low frequency) modulation and demodulation unit, an MB (medium frequency) modulation and demodulation unit, an HB (high frequency) modulation and demodulation unit, a cellular information processing unit, a cellular information storage unit, and a cellular transmission control unit.

[0323] The Bluetooth processing unit includes a Bluetooth modem unit, a Bluetooth information processing unit, a Bluetooth information storage unit, and a Bluetooth transmission control unit.

[0324] According to a second aspect of this application, as shown in FIG20, an aerosol generating device is provided, comprising spliced ​​metal shell segment 100 and non-metal shell segment 300, as well as antenna module 200 in any of the above embodiments.

[0325] The antenna module 200 is housed within the cavity after the metal housing section 100 and the non-metal housing section 300 are assembled.

[0326] In Figure 20, the metal shell section 100 and the non-metal shell section 300 are in a separate state. After the metal shell section 100 and the non-metal shell section 300 are spliced ​​together, the antenna module 200 is housed in the cavity after the metal shell section 100 and the non-metal shell section 300 are assembled.

[0327] The metal housing 100 serves as the reference ground for the entire device. Each unit in the antenna module 200, such as the RF transceiver unit, the feed unit, the coupling and tuning unit, and the radiator, generally has corresponding grounding design requirements based on its own electrical connection design requirements. At this time, the electrical connection between the corresponding unit and the metal housing 100 can be achieved through appropriate structural design and circuit board routing design, thereby fulfilling the grounding design requirements of the corresponding unit.

[0328] In this embodiment, the metal shell segment 100 and the non-metal shell segment 300 are elliptical cylinders. However, in other embodiments, the metal shell segment 100 and the non-metal shell segment 300 can also be square cylinders, rectangular cylinders, cylinders, etc. Furthermore, the metal shell segment 100 and the non-metal shell segment 300 do not have to be strictly uniform cylinders. They can be designed with different shapes in different locations according to product ID, function, and other design requirements. For example, based on the human hand grip, certain local areas in the middle of the metal shell segment 100 and the non-metal shell segment 300 can be recessed to facilitate the human hand gripping the device. Or, the top or bottom of the metal shell segment 100 and the non-metal shell segment 300 can be arc-shaped to achieve the desired appearance.

[0329] The aerosol generating device in this application includes an antenna module equipped with a cellular IoT antenna and a corresponding cellular radio frequency transceiver unit. Through the cellular radio frequency transceiver unit, cellular electromagnetic wave signals received from the outside can be fed back to the cellular radio frequency transceiver unit and cellular radio frequency signals output by the cellular radio frequency transceiver unit can be transmitted to the outside, ultimately realizing cellular IoT communication.

[0330] As shown in Figures 21 and 22, optionally, the cellular IoT antenna includes a first cellular radiator 111 and a second cellular radiator 112. The radio frequency range covered by the first cellular radiator 111 is different from that of the second cellular radiator 112. The first cellular radiator 111 is electrically connected to the cellular radio frequency transceiver unit 120. The second cellular radiator serves as a parasitic unit of the first cellular radiator. It should be noted that a corresponding cellular feed unit should usually be included between the first cellular radiator 111 and the cellular radio frequency transceiver unit 120. Although it is not shown in Figures 21 and 22, it does not mean that it is not provided in this embodiment. The non-metallic shell section 300 is columnar, and the inner wall of the non-metallic shell section 300 is divided into a circumferentially distributed first inner wall 301 and second inner wall 302.

[0331] The first honeycomb radiator 111 is arranged around the first inner wall 301, and the second honeycomb radiator 112 is arranged around the second inner wall 302.

[0332] As can be seen from the assembly relationship of the first honeycomb radiator 111 and the second honeycomb radiator 112 shown in Figures 21 and 22, the first honeycomb radiator 111 and the second honeycomb radiator 112 do not overlap in the axial direction of the non-metallic shell section 300, thereby enabling the first honeycomb radiator 111 and the second honeycomb radiator 112 to have better overall performance.

[0333] Optionally, the antenna module also includes a flexible printed circuit board (FPC) that integrates a first metal wiring and a second metal wiring.

[0334] The first metal wiring serves as the first cellular radiator, and the second metal wiring serves as the second cellular radiator.

[0335] Referring to Figures 21 and 22, since the first honeycomb radiator 111 and the second honeycomb radiator 112 need to be arranged according to the inner wall shape of the non-metallic shell segment 300 to improve overall performance, a flexible circuit board can be used to efficiently obtain the desired shape. Of course, in other embodiments, the first honeycomb radiator 111 and the second honeycomb radiator 112 can also be implemented using surface metallization processes such as LDS and PDS, or using processes such as metal sheets and insert molding, without specific limitations.

[0336] Optionally, the aerosol generating device may also include a printed circuit board at least partially housed within a non-metallic housing segment, and electrical connections integrated on the printed circuit board.

[0337] The cellular radio frequency transceiver unit and the cellular feed unit are integrated on a printed circuit board and electrically connected to electrical connectors.

[0338] The cellular IoT antenna is fixed and electrically connected to the electrical connector.

[0339] In this embodiment, the cellular radio frequency transceiver unit is usually present as an integrated chip. In order to enable it to be better electrically connected to other devices, the required electrical connection is achieved by using various metal lines on the printed circuit board.

[0340] The integrated chip corresponding to the cellular radio frequency transceiver unit usually has a small number of pads, which cannot be directly electrically connected to the cellular IoT antenna. Therefore, to address this issue, corresponding electrical connectors are integrated on the printed circuit board to achieve a reliable electrical connection between the cellular radio frequency transceiver unit, the cellular feed unit, and the cellular IoT antenna.

[0341] The shape, placement, and orientation of the printed circuit board (PCB) are determined based on the structural characteristics and assembly relationships of the various components inside the aerosol generating equipment, and there are no specific restrictions. The PCB can also be replaced by other types of materials, substrates, and substrate processes, including ceramic substrates, carrier boards, LTCC, HTCC, etc., and can also be implemented using flexible printed circuit boards.

[0342] As shown in Figure 23, optionally, the cellular IoT antenna includes a first cellular radiator 111 and a second cellular radiator 112, wherein the radio frequency range covered by the first cellular radiator 111 is different from that of the second cellular radiator 112; the antenna module also includes a first cellular tuning unit 131 and a second cellular tuning unit 132; electrical connectors include a first connector 141, a second connector 142, and a third connector 143; and printed circuit boards include a first printed circuit board 151 and a second printed circuit board 152. The first connector 141 and the first cellular tuning unit 131 are electrically connected and integrated on the first printed circuit board 151, and the first cellular radiator 111 is fixed and electrically connected to the first connector 141.

[0343] The cellular radio frequency transceiver unit 120 and the second connector 142 are electrically connected and integrated on the second printed circuit board 152, and the first cellular radiator 111 is fixed and electrically connected to the second connector 142.

[0344] The third connector 143 is electrically connected to and integrated with the second cellular tuning unit 132 on the second printed circuit board 152. The second cellular radiator 112 is fixed to and electrically connected to the third connector 143.

[0345] In this embodiment, the second cellular radiator 112 serves as a parasitic unit of the first cellular radiator 111. Furthermore, a corresponding coupling and tuning unit can be added between the first cellular radiator 111 and the second cellular radiator 112. In other embodiments, a transceiver unit electrically connected to the second cellular radiator 112 can be added, allowing the second cellular radiator 112 to operate independently. For example, the second cellular tuning unit 132 can be replaced with a corresponding transceiver unit.

[0346] The first printed circuit board 151 can serve as the main board, and the second printed circuit board 152 can serve as the secondary board. In addition to integrating the aforementioned components, the first and second printed circuit boards 151 and 152 also integrate various functional circuits within the aerosol generating device, such as power supplies, processors, heating circuits, temperature measuring circuits, charging circuits, and data transmission circuits. Furthermore, the number, size, shape, and relative positions of the printed circuit boards to be placed inside the aerosol generating device are determined based on a comprehensive consideration of factors such as the internal stacking of the aerosol generating device, the performance requirements of each functional circuit, and cost, and are not limited to the first and second printed circuit boards 151 and 152 mentioned above.

[0347] In Figure 23, the cellular RF transceiver unit 120 is integrated on the second printed circuit board 152, which allows the cellular RF transceiver unit 120 to be more conveniently electrically connected to the second connector 142 corresponding to the first cellular radiator 111. Of course, in other embodiments, the cellular RF transceiver unit 120 can also be integrated on the first printed circuit board 151. In this case, the electrical connection between the cellular RF transceiver unit 120 and the second connector 142 can be achieved through an RF transmission line. Typical RF transmission lines include RF coaxial cables, RF transmission lines based on flexible circuit board designs, etc.

[0348] Among them, the first connector 141, the second connector 142, and the third connector 143 can all be in the form of spring clips. The spring clips can be pre-formed components or customized designs based on the internal space characteristics of the aerosol generating device, and are not limited to the shape and size of the spring clips shown in Figure 24. There are no specific restrictions on how the spring clips are placed inside the aerosol generating device. They can be integrally injection molded with plastic and fixed inside the aerosol generating device, achieving electrical connection with the first printed circuit board 151 and the second printed circuit board 152 after assembly. Alternatively, they can be integrally assembled using the structural characteristics of the various components inside the aerosol generating device, fixing the spring clips inside the aerosol generating device, achieving electrical connection with the first printed circuit board 151 and the second printed circuit board 152 after assembly. Alternatively, the spring clips can be directly integrated onto the first printed circuit board 151 and the second printed circuit board 152 using SMT or soldering methods before being assembled into the aerosol generating device. The spring needs to be made of metal, and there are no restrictions on the specific type of metal. Stainless steel or copper is preferred. In addition, various surface treatments can also be applied to the metal material for the spring. The spring can also be replaced by other components with elastic characteristics, as long as they can be electrically connected to the first honeycomb radiator 111 and the second honeycomb radiator 112, the first printed circuit board 151 and the second printed circuit board 152, such as a Pogo pin or a probe.

[0349] The first printed circuit board 151 integrates a first cellular tuning unit 131, and the second printed circuit board 152 integrates a second cellular tuning unit 132 and a cellular radio frequency transceiver unit 120. Generally, the first cellular tuning unit 131, the second cellular tuning unit 132, and the cellular radio frequency transceiver unit 120 all need to be grounded. Referring to Figure 21, the metal housing segment 100 serves as the reference ground. Therefore, both the first printed circuit board 151 and the second printed circuit board 152 can be electrically connected to the metal housing segment 100. The number and location of the first printed circuit board 151 and the second printed circuit board 152 electrically connected to the metal housing segment 100 can be set according to the internal structural characteristics of the aerosol generating device. Generally, the more grounding points there are, the more beneficial it is for radio frequency signal transmission and the antenna reference ground. However, the more internal space is occupied by the aerosol generating device, the more difficult it is to manufacture and assemble. The specific number and location of grounding points need to be determined by a trade-off between the working effect of each electronic unit of the aerosol generating device, the structural space occupied, and the difficulty of manufacturing and assembling the device. There are no specific restrictions on the way the first printed circuit board 151 and the second printed circuit board 152 are electrically connected to the metal housing section 100. Interference fit, welding, snap-fit, mortise and tenon, screw locking, etc. are all acceptable and can be set according to the internal structural characteristics of the equipment.

[0350] As shown in Figure 25, optionally, the cellular IoT antenna includes a first cellular radiator 111 and a second cellular radiator 112. The radio frequency range covered by the first cellular radiator 111 is different from that of the second cellular radiator 112. A corresponding first cellular feed unit is typically included between the first cellular radiator 111 and the first transceiver subunit 121. Similarly, a corresponding second cellular feed unit is typically included between the second cellular radiator 112 and the second transceiver subunit 122. Although not shown in Figure 25, this does not mean that it is not included in this embodiment. As shown in Figures 25 and 26, the antenna module also includes a coupling and tuning unit 133; the electrical connectors include a fourth connector 144 and a fifth connector 145.

[0351] The fourth connector 144 is electrically connected to the first transceiver subunit 121 and integrated on the first printed circuit board 151. The first honeycomb radiator 111 is fixed to and electrically connected to the fourth connector 144.

[0352] The fifth connector 145 is electrically connected to and integrated with the second transceiver subunit 122 on the first printed circuit board 151, and the second honeycomb radiator 112 is fixed to and electrically connected to the fifth connector 145.

[0353] The coupling tuning unit 133 is integrated on the first printed circuit board 151 and is electrically connected to the fourth connector 144 and the fifth connector 145, respectively.

[0354] The specific details involved in this embodiment can be referred to in the above embodiments, and will not be repeated here.

[0355] As shown in Figure 27, optionally, the antenna module also includes a Bluetooth antenna and a Bluetooth radio frequency transceiver unit 161; the electrical connector also includes a sixth connector 146.

[0356] Referring to FIG20, the non-metallic shell section 300 is columnar, and the Bluetooth antenna includes a first section 162 arranged along the circumferential direction of the non-metallic shell section 300 and a second section 163 arranged along the axial direction of the non-metallic shell section 300.

[0357] The Bluetooth radio frequency transceiver unit 161 and the first segment 162 of the Bluetooth antenna should usually also include a corresponding Bluetooth power supply unit, although it is not shown in Figure 27, but this does not mean that it is not set in this embodiment.

[0358] As mentioned in the above embodiments, the first cellular radiator 111 and the second cellular radiator 112 are also arranged along the circumferential direction of the non-metallic shell segment 300. Therefore, in this embodiment, the first segment 162 in the Bluetooth antenna can be understood as being basically parallel to the first cellular radiator 111 and the second cellular radiator 112, and the second segment 163 in the Bluetooth antenna can be understood as intersecting with the first cellular radiator 111 and the second cellular radiator 112.

[0359] The sixth connector 146 is electrically connected to the Bluetooth radio frequency transceiver unit 161 and integrated on the first printed circuit board 151. The second segment 163 in the Bluetooth antenna is fixed and electrically connected to the sixth connector 146 through the first segment 162.

[0360] The specific details of cellular communication involved in this embodiment can be found in the above embodiments, and will not be repeated here.

[0361] In this embodiment, the Bluetooth antenna uses a metal wire and is divided into a first segment 162 and a second segment 163. In other embodiments, it can also be implemented using FPC, LDS, PDS, Insert Molding, metal sheets, etc. In addition, the Bluetooth antenna can also be implemented using a ceramic antenna, soldered to a printed circuit board inside the aerosol generating device. There are no fixed limitations on the implementation method.

[0362] As a supplement, when the antenna scheme of this application is applied to the aerosol generating device, the performance curves of the antenna module after impedance matching obtained by simulation are shown in Figures 28 to 30. The total efficiency of the low-frequency cellular IoT antenna is above -9.41dB, the total efficiency of the mid-to-high frequency cellular IoT antenna is above -6dB, and the total efficiency of the Bluetooth antenna is above -4.1dB. Overall, the antenna scheme and design can well meet the system requirements of the aerosol generating device in both cellular IoT communication and Bluetooth communication.
